Comment (by mlennert):

 A colleague who was trying to vectorize +/- 13 mio segments (output of
 i.segment) just ran into the same problem of memory saturation during the
 topology creation phase.

 The tiling approach is interesting, we will look into that, but it would
 be nice if a possibility was found to make the whole r.to.vect process
 more efficient. I have no idea, how, though...
